"They have been seeing each other since All-Star Weekend in February," a source close to the two said, reports aceshowbiz.com.

"It's very early in the relationship and he's very young, so she is just having fun. She likes hanging out with boys that she can have fun with and that's what Terrence is to her. I don't think it will develop into anything serious, they are just enjoying getting to know one another," the insider added.

The dating rumour first emerged when Toronto Raptors' Ross posted on Instagram a photograph of himself standing next to Rose, whom he called his "woman crush Wednesday".
